Question

What is the mean of the data set rounded to the nearest tenth

1.2, 1.8, 1.6, 1.4, 1.4, 2.2
A: 1.4
B: 1.5
C: 1.6
D: 9.6​

Answer 1

C

Explanation:

add all the data pieces together which equals to 9.6

divide by the number of data pieces: 6

9.6/6= 1.6

Answer 2

Option: C is the correct answer.

The mean of the data set is: 1.6

Explanation:

The mean of the data set is the average value of the data set.

It is calculated as the ratio of the sum of all the data values to the number of data points.

Here we have the data set as:

1.2, 1.8, 1.6, 1.4, 1.4, 2.2

There are a total of 6 data points.

and the sum of these data points is: 1.2+1.8+1.6+1.4+1.4+2.2= 9.6

Hence, the mean of the data set is:

`Mean=(9.6)/(6)\\\\i.e.\\\\Mean=1.6`
